Benefits of technology

[0021] Furthermore, the battery circuit is configured with a circuit board. After the circuit board is provided on a shorter side face of the rechargeable battery, the rechargeable battery and the circuit board are integrated with each other. As a result, the operation of housing the rechargeable battery and the circuit board within the outer case is facilitated.
[0022] Furthermore, the battery circuit is co...

Embodiment Construction

[0031] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. The following embodiment is merely an example embodying the present invention, and therefore does not limit a technical scope of the present invention.

[0032]FIG. 1 shows a structure of a battery pack according to the first embodiment. The battery pack is formed so that a flat prismatic lithium ion rechargeable battery (hereinafter, referred to as a rechargeable battery) 1 and battery circuit components such as a circuit board 2 constituting a battery protecting circuit for protecting the rechargeable battery 1 from overcharge, overdischarge and the like are housed within an outer case 10 formed by bonding an upper case 7 and a lower case 8, each being formed as a half-shell body, to each other. The battery pack is intended to be reduced in thickness so as to meet the requirements of reduction in thickness of portable el...

Abstract

An outer case (10, 20, 35, 40) for housing a rechargeable battery (1, 31, 41) and a battery circuit therein is composed of an upper case (7, 21, 42) and a lower case (8, 22, 43), each being formed as a half-shell body. The respective bottom faces of the upper case (7, 21, 42) and the lower case (8, 22, 43) are formed of film members (7b, 8b, 32, 34, 42b, 43b), and are integrally formed with resin moldings (7a, 8a, 33, 42c, 43c) forming circumferential side faces.

Description

TECHNICAL FIELD [0001] The present invention relates to a battery pack which is reduced in size, weight, and thickness so as to be used as a battery power source for portable electronic equipment that is increasingly reduced in size as well as in thickness. BACKGROUND ART [0002] There is an increasing demand for reduction in size, weight, and thickness of portable information equipment and portable audio equipment such as a portable telephone and a mobile computer so as to improve their portability. It would not be an exaggeration to state that a battery power source is the key to realize such a reduction. In particular, there is a strong demand for reduction in weight and thickness of a battery power source device using a rechargeable battery. [0003] As a rechargeable battery constituting a battery power source device of portable equipment, a nickel-cadmium battery, a nickel metal hydride battery, and a lithium ion rechargeable battery are used. Above all, the lithium ion rechargea...
